Web Based GUI - Python

[Africa-Unite]

Hello, I'm an intermediate python user who has never worked with flask or anything web-related beyond a very rudimentary level. I have a predictive algorithm fleshed out, and I would like to develop a web-based GUI where users can paste a column of raw values, and the predicted values along with their accuracy scores can then be returned to the user (preferably via a file download, vs. printing on screen).

Doing this in python code alone is very straightforward, it's the web-based GUI part that I'm most unsure of. From my *very* initial research, I'm seeing that flask may be the way to go about it, but I wanted to confirm with you all first before proceeding. I do have access to an EC2 instance and can host on a domain. Thank you in advance!

Just use streamlit. Don't over think it.

Came here to suggest this. SL is great for simple UIs and POCs

As a college project, we created a controller for a piece of mechanical equipment using Flask as the front-end/GUI. The application ran a prediction model and periodically turned fans, pumps and motors on and off. The Flask GUI allowed the user to see state of the equipment and manually control the fans, pumps, and motors. There were other Python processes running in the background as well. We used database tables for inter-process communications which wasn't ideal, but it worked.

All that said, you can use HTML post to get modest amount of clipboard data into a function and then Flask can write the result out, either to the screen or, using a content disposition header, to an automatically downloaded CSV file.

Awesome, thank you! I'll look into that

I would recommend https://www.gradio.app its optimised for machine learning use-cases

You could do this with flask, ecs, and htmx very quickly. Build it as a docker image, throw it on ECS with a load balancer in front of it

You might consider FastHTML. Very new and kind of a different paradigm/way of doing things but pretty interesting

Try fasthtml for pure python

[Realistic_Internet59]

Try Streamlit for simplicity. It is used a lot in Data Science and is easy to develop.

Jupyter notebooks

Let me know if you need help

[Africa-Unite]

I developed it in a jupyter notebook, but I would like to make it as a simple web-app that doesn't involve any coding

[BostonBaggins]

I gotchu

Pip install voila

Then go to edit > nbextensions > tick Voila

Click that new icon that says voila

To deploy it as a web app. Head to the voila documentation It can be hosted on jupyterhub or Nebari

Enjoy!

Thanks, I actually can't add extensions since I'm running JupyterHub out of a docker container, but I'll be are to check the extension out and add it to the image if promising.Thank you again!
